Power Automate: Desktop flows - Debug flows using variable default values

This feature introduces advanced debugging support by allowing you to assign default values to variables directly within the desktop flow designer. During debugging sessions, when you are starting the execution from a specific step of the automation, the assigned default values are automatically applied, enabling you to test specific scenarios without modifying actions or rerunning the flow from the beginning. This is especially useful when working with complex logic, conditions, or branches that depend on variable state.

The feature is enabled automatically. To use it, edit a variable in the designer and define a default value for debugging. The value is applied only during debug runs and does not affect production executions. You can disable the behavior at any time by clearing the default value, restoring standard variable handling.

Business Value

This feature is for makers who build and maintain complex desktop flows. You can test and troubleshoot flows faster by setting variable default values directly in the designer, instead of restarting runs or manually preparing inputs each time. This reduces debugging time, lowers frustration, and helps you iterate more confidently whe…
